how long are foglight bulbs supposed to last?? i changed mine in november and one has already burned out. is that normal?

 

I put my PIAAs on and one burned out in about two months

I took the foglight off and took it apart - some water got in there and corroded the wires and caused the bulb to fail I'm going to seal it with silicone when I put the new bulb in. You'd think they could do a better job of sealing the lights - especially for the money of PIAAs. My other fog is OK - but I'm gonna check it too!
